Porcelain-fused-to-zirconia is a high-quality alternative to porcelain-fused-to-metal. With zirconia's high flexural strength of 1,450 MPa, these restorations offer a durable base to support the high esthetics of porcelain. Our CDTs craft PFZs by layering porcelain over a zirconia substructure. Due to the natural translucency of zirconia, there is no need to worry about the common esthetic challenges that accompany PFM crowns, such as discoloration or the dark line that can appear along the gingiva. They are hypoallergenic and biocompatible. We utilize CAD/CAM technology to ensure they offer consistent and accurate fit for every case.

A CAD/CAM substitute for traditional PFM, our porcelain-fused-to-zirconia can be used for anterior and posterior crowns, crowns over implants, and bridges of up to fourteen units.

  • Attachment cases
  • Cases with less than 1 mm clearance
  • Bruxism
  • Patients who have broken a PFM crown
  • Cases that require bonding

The ideal preparation for PFZs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.

  • Resin Ionomer cement (RelyX or RelyX Unicem, 3M ESPE)
  • Maxcem Elite (Kerr)
  • Panavia F 2.0 (Kuraray) - ideal for short, tapered preparations
  • Glass ionomer cement (GC Fuji, GC America)

If an adjustment is required on the ceramic, use a fine diamond with water and air to keep the crown cool. To contour the ceramic, polish with a pink rubber wheel and diamond polishing paste (Brasseler, Shofu, Vident).
